Double Tube Core Barrel

Universal Engineering Works manufacture complete range of Double Tube Core Barrel as per DCDMA and British Standard.

Double Tube Core Barrels are swivel head i.e the inner tube is attached with the core barrel head through bearings which makes the rotation of the inner tube independent of the core barrel.

Water in the double tube core barrel passes in between the outer tube and inner tube. Perforation at the lower end of the inner tube permits the flow of water. From this point to the diamond core bit represents the only place where the core is subject to erosion. This distance is very small as compared to the total length of the double tube core barrel. With the elimination of the erosion problem, it becomes possible to take core of softer and broken materials. It offers higher percentage of core recovery and little erosion of core.

UEW manufacture the following Core Barrels as per DCDMA , BRITISH standard etc.

EX, AX, BX, NX, HX, EWG, AWG, BWG, NWG, HWG, BWT, NWT, HWT, AWM, BWM, NWM, NXM, T2-66mm, T2-76mm, T2-86mm, HWF, HWG

NWM Double Tube Core Barrel or NXM Double Tube Core Barrel and HWF Double Tube Core Barrel use face discharge diamond core bits. These double tube core barrels offer high core recovery as diamond core bits have hole at the face of the crown.
